Footnotes

  • Provenance:
    The War Museum

    WWII era torpedoes using these gyros could be fired from a submarine, surface ship, PT boat or dropped from an aircraft. The gyro kept the torpedo headed on a straight course, not allowing it to go in circles. Sperry's gyrocompass evolved through many models and was in huge demand during World War II. The Sperry gyrocompass revolutionized navigation on land, sea and air.
